Covid league rules question

My league is concerned that an increased bench size will favor the skilled fantasy player. Most are in favor of reducing the bench size. This would make the free agent pool a little more rich.

We are personally not making any changes to rosters except adding a few extra IR spots that can only be used for COVID related instances and if anyone is found breaking that honor system transactions could be reversed to correct it. We are basically saying that the players should be taking every precaution they can, just as if they would to avoid getting sick from anything else, or injured. But by adding a few extra IR spots, it seemed to alleviate the concerns. And just like any other IR rule, once cleared from COVID roster must be correct and removed from IR, or commish removes the player from their roster.
